Considering the endothermic dissociation of CaCO3 in a closed vessel (CaCO3 ⇌ CaO + CO2), the pressure of CO2 increases, if____________________?
Correct answer: B. The temperature is increased
- A. A catalyst is added
- B. The temperature is increased
- C. An inert gas is pumped keeping the temperature constant
- D. None of these
Explanation
Raising temperature favors the endothermic decomposition of CaCO3, increasing the equilibrium partial pressure of CO2. A catalyst does not change equilibrium, and an inert added at constant volume does not change CO2 partial pressure.
